error trying to connect: invalid dnsname - in Kubernetes

[jlpettersson]

I cross-compiled this on MacOS to aarch64 and deployed to a local kind-cluster.
I built it with rustls for kube-rs with this line in Cargo.toml

[dependencies]
kube = { version = "0.57.0", default-features = false, features = ["client", "rustls-tls"] }

But I get many log-lines with this error:

ERROR HTTP{http.method=GET http.url=https://10.96.0.1:443/apis/apps/v1/namespaces/default/deployments? otel.name="list" otel.kind="client" otel.status_code="ERROR"}: kube::client: failed with error error trying to connect: invalid dnsname

This is when I run the version-app as a Deployment in Kubernetes.

Is this something expected? Is it a bug?

rustls is only supported in-cluster because of kube-rs/kube#153. In cluster support also requires kube 0.59.0 that was just released.

@kazk Thanks!

When using 0.59.0 on the dependencies, I got this working.
